Probability

The probability of two dependent events A and B is the probability of A times the probability of B after A occurs. A card is chosen at random from a standard deck of 52 playing cards. Without replacing it, a second card is chosen. What is the probability that the first card chosen is a queen and the second card chosen is a jack? The probability that the first card is a queen is 4 out of 52. However, if the first card is not replaced, then the second card is chosen from only 51 cards. Accordingly, the probability that the second card is a jack given that the first card is a queen is 4 out of 51. The outcome of choosing the first card has affected the outcome of choosing the second card, making these events dependent.
